Application January 16, 1933, Serial No. 651,903

1 Claim. (01. -153) My invention has for its object the provision of anextremely simple and highly efficient mop holder for attaching a mophead or swab to a mop stick.

To the above end, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claim.

In the accompanying drawing, which illustrates the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawing:

Fig. l is a plan view of the improved mop head holder with some partsbroken away and sectioned and holding a mop head fragmentarilyillustrated by means of broken lines;

Fig. 2 is a view corresponding to Fig. 1, with the exception that someparts are shown in different positions by both full and broken lines;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. l

Fig. 4 is an elevation of the outer end of the improved mop head holderwith the relatively fixed clamping bar shown in another position bymeans of broken lines; and

Fig. 5 is a view partly in elevation and partly in section taken on theline 55 of Fig. 2.

The numeral 6 indicates a mop stick, to one end of which is rigidlysecured the improved mop head holder. This mop head holder comprises afork l, a relatively fixed clamping bar 8, a relatively movable clampingbar 9, and a screwthreaded operating rod [0 to which is applied aco-operating thumb-nut I I. A mop head Z, diagrammatically illustratedby means of broken lines in Fig. 1, is inserted between the clampingbars 8 and "9, which are partly separated. Ob- Viously, by turning thethumb-nut II, in the proper direction on the screw rod Ill, the movableclamping bar 9 will be moved bodily toward the fixed clamping bar 8 tohold the head Z tightly clamped therebetween.

The fork l is made up of a pair of flat metal bars and a pressed metalcrown piece l2, that is channel-shaped in cross-section. These bars areshaped, at one of their end portions, to form the two prongs 13 of thefork l, which prongs are parallel, and the intermediate portions of saidbars are in converging relation and form, together with the crown piece12, the transverse portion of the fork l. The other or inner endportions of the bars are parallel and one end portion of the stick 6projects therebetween and is rigidly secured thereto by a pair of rivetsl4. The bars, at the transverse portion of the fork I, extend throughthe end portions of the crown piece 12,

and the sides of said piece are folded thereover to rigidly secure thecrown piece [2 to the bars.

A hole 15 for a purpose that will presently appear, is formed in thebottom of the crown piece [2 in axial alignment with the stick t. Thefree end portions of the prongs [3 are reduced in transverse width, seeFig. i, and bent laterally toward each other to afiord a pair ofretaining lugs IS. The clamping bars 8 and 9 extend endwise between theprongs l3 and each thereof, in crosssection, is in the form of a yoke ofsuch transverse dimensions as to permit the fixed clamping bar 8 to seatwithin the movable clamping bar 9. Both clamping bars 8 and 9 are inwardof the lugs I6, and the fixed clamping bar 8, at its end portions,straddles said lugs and is normally held thereby against outwardmovement. A hinge pin ll connects the fixed clamping bar 8, at one ofits ends, to one of the lugs It, for outwardly swinging movement in theplane of the fork T' when released from the other of said lugs.

The fixed clamping bar 8 has sufficient loose play at its hinge pin H topermit said bar, when its free end portion is lifted out of interlockingengagement with the respective lug I6, as indicated by broken lines inFig. 2, to be moved angu larly transversely of the plane of the fork l,as indicated by broken lines in Fig. 4, so as to clear said lug and beswung outwardly, as indicated by full lines in Fig. l.

The clamping bar 9 is guided by the prongs I3 and cooperating guide lugsl8 for bodily movement toward or from the fixed clamping bar 8. Theguide lugs l8 are formed in pairs on the ends of the movable clampingbar 9 and the prongs i3 extend longitudinally therebetween. Outwardly ofthe prongs E3, the guide lugs I8 of each pair are bent laterally towardeach other and substantially completely embrace the respective prong 13.

One end of the screw rod I0 is rigidly secured to the movable clampingbar 9 at the longitudinal center thereof, and at its other end portionloosely extends through the hole IS. The thumb nut H is applied to thescrew rod it between the movable clamping bar 9 and the crown piece l2and engages said crown piece as a base of resistance to positively holdsaid bar against movement away from the fixed clamping bar 5%.Obviously, when the thumb nut ll ismoved longitudinally on the screw rod10, away from the crown piece l2, the movable clamping bar 9 may bemoved manually away from the fixed clamping bar 8, and at which time,the screw rod Ill will loosely move endwise through the hole I5.

prongs I3. On each end of the clamping bar 9 isa pair of transverselyspaced stop shoulders 25 for the respective prong IS. The passageways itare between the stop shoulders 20 of said pairs and are narrower thanthe transverse width of the prongs H3. The purpose of the stop shoulders20 is tohold the prongs I3 properly spaced and against inward lateralmovement. In case the screw-threads on the rod l I! wear to such anextent that they are no longer efficient, said rod may be removed fromthe mop head by removing the hinge pin IT to detach the fixed clampingbar 8, and. then withdrawing the movable clamping bar 9 from the prongsl3 and the screw rod H] from the crown piece l2. With the removal of themovable clamping bar 9 and its screw rod 10, a new bar and rod may besubstituted therefor.

At the time the movable clamping bar 9 is removed from the prongs l3,the lugs l 6 freely pass through the passageway I9.

What I claim is:

In a mop head, a fork having a pair of prongs provided at their endswith inturned retaining lugs, a relatively fixed clamping bar normallyheld on the retaining lugs, and a movable clamping bar between theprongs and having on each end a pair of guide lugs, said guide lugs,outwardly of the prongs, being bent around said prongs, said movableclamping bar having adjacent each end between the respective lugs a pairof transversely spaced stop shoulders and also having between each pairof stop shoulders a notch-like passageway for the respective inturnedlug, said prongsbeing wider, transverse to the plane of the fork, thanthe inturned lugs and the stop shoulders engaging the prongs.
